utterly inadequate intelligence

This is a quote from A. Einstein that I just found - I was actually fortunate enough to have figured this out at some point (probably while I was preparing for the final exams of my physics masters degree, man did that prove to me how utterly inadequate my intelligence is!):

One has been endowed with just enough intelligence to be able to see clearly how utterly inadequate that intelligence is when confronted with what exists. If such humility could be conveyed to everybody, the world of human activities would be more appealing.
